Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533514, here are decompositions:

3 + 31533511 = 31533514
17 + 31533497 = 31533514
53 + 31533461 = 31533514
83 + 31533431 = 31533514
101 + 31533413 = 31533514
347 + 31533167 = 31533514
641 + 31532873 = 31533514
647 + 31532867 = 31533514

Showing the first eight; more decompositions exist.
